Okay...so I thought I knew what I was doing! I just bought and installed a pair of Pro Comp 7" Motorsports driving lights on my front bumper. I wired them up as I have before with other vehicles (i.e. proper grounding, in-line 30 amp fuse, blah-blah). The problem is everytime I flip the switch to turn them on I pop the 30a fuse. Help!! What in the name of all that is decent am I doing wrong? :flame:

Did you modify the factory wire harness? You have 2 lights connected together correct?

SOunds like you may have a direct short somewhere. Did you use the stock wiring harness? Accidently miss wire the ground on the relay ?

If you're blowing a 30amp fuse immediately upon throwing the switch, you've got a direct short somewhere.

Re-check your wiring and make sure that you don't have a pinched hot lead or direct short somewhere. Sorry, but troubleshooting wiring without actually seeing it is tough, at best, but with your description it sounds pretty cut and dry, regarding a short...

Also, you should be using a relay if the lights require 30 amps. Double-check the relay connections and make sure that the power is on the right post, etc..

EDIT: Looks like NCFJ posted while I was typing. But, came to the same possible causes...

A relay huh? The wiring kit I purchased along with the lights did not come with a relay. I think you guys are right about the short though. I will check that. Thanks once again guys....ya'll are the reason this forum is so darn great!

You really should use a relay in your light circuit. They are easy to wire in and save you from running a heavy wire from the battery to the switch and then back out to the lights (asuming they are on the front bumper area). Check out the thread below for a basic schematic.
